When hydrogen fuses into helium a photon of light is produced. The material at the center of the sun is very dense so as the photon travels on its way out of the sun it constantly runs into atoms. It is absorbed and then emitted again. This can happen many millions of times. Some estimates for the time it takes the photon to reach the photosphere range from several thousand years to several million years.
Once the photon leaves the sun it takes about 8 minutes to travel the 145 million km from the sun to the earth.
It then hits the object in question and depending on the what wavelength of the photon is either absorbed or reflected. Lets assume the object is red. If the photon has a wavelength of 650 nm (red light) it will be reflected. If it is 450 nm (blue light) it will be absorbed.
The red light then travels from the object to your eye and hits the retina of your eye. It then hits one if the two types of detectors in your eye, cones for colour and rods for low level light detection. A signal then goes from you eye to your brain through the optic nerve to the visual cortex in the brain.

Does the sun or earth emit light with higher energy?
Only the sun emits radiation in the wavelengths of visible light, which is considerably higher energy than infrared emitted by Earth.
The two most important processes by which energy is transported from the core of the Sun to the photosphere are?
Solar energy is practically light. Light travels through waves. But yes, solar energy is light. It brings heat to the earth, which is solar energy.
How does light and energy get from the sun to the earth?
It comes on electromagnetic waves.
How does energy from the sun travel to the earth?
Most of the energy generated by the Sun travels to Earth as Electromagnetic Radiation. A very tiny amount of energy of the Sun is given off as particles, mostly electrons and protons, flying off into space.Electromagnetic energy is, of course, light. The light energy from the Sun includes the visible spectrum we can see and much more in the infrared part of the spectrum that we can not see and a little in the ultraviolet as well. It all travels at the speed of light from the Sun outwards and a tiny fraction of the Sun's energy strikes the Earth and is absorbed. As a result, the electromagnetic energy is converted to thermal (heat) energy and keeps Earth warm.
What form does suns energy have when it reaches earth?
The Sun's energy is given out mainly as "electromagnetic radiation". Light is a form of electromagnetic radiation. Heat is the main form the Sun's energy has when it reaches Earth, particularly the Earth's surface.
What did energey from the sun travel to Earth as?
Energy from the sun to Earth travels as electromagnetic energy, or light energy.
What is the primary source of light of all light energy on earth?
it is the sunThe Sun
How long will it take earth to get to the sun?
It will take 8 minutes for the light from the sun to reach Earth. The actual heat of the sun does not reach all the way out to Earth. The warmth on Earth comes from the conversion of light energy to heat energy.
How is the sun a form of light energy?
it gives the earth light and warmth.
What dose earth get from the sun?
Energy in the form of light.
What is the source of light and heat energy for the earth?
The sun
What type of energy is collected from the sun?
The energy collected from the sun is called solar energy. The energy gets to the earth from the sun by radiation that has been affected by the earth's atmosphere.
Is a flashlight good model for suns light energy hit earth?
Flashlight is not good model to test sun light hit earth. The light of flashlight is too small energy to compare sun light.
What is the ultimate energy for all the life on earth?
probably the sun......?
What does the Sun's energy do to the Earth?
All life on Earth depends on the sun's light. Without it we would die.
Does the sun or earth emit light with higher energy?
Only the sun emits radiation in the wavelengths of visible light, which is considerably higher energy than infrared emitted by Earth.
What provides energy for all life on earth?
The sun's light energy I think...
